This dragon lair is inhabited by a level-dependent dragon. There is an alchemy lab on the altar in the middle of the lair, one urn, and one burial urn. At the top of the main stairway in the center of the lair is a word wall which teaches part of the Ice Form shout.

Mount Anthor was the site of the battle between Olaf One-Eye and the dragon Numinex which occurred during the First Era.

The path southwest up the mountain to the lair continues to the south, then east, looping back to the Shrine of Azura. It appears that the dragon caught a party of refugees in the open on this path. Their three bodies, along with a wrecked cart piled up with their belongings, can be found partially buried in the snow. Among the detritus are a few useful items: a coin purse, an apothecary's satchel, a leveled battleaxe, and a copy of the Enchantingskill bookEnchanter's Primer.

If the dragon at the wall is the subject of a bounty, it may not appear after the main quest has been completed.

The compass' quest marker for this location may become bugged, telling you to go west to Markarth, but the map will be pointing to the correct location. If you follow the marker into Markarth, it changes to the bold arrow and points toward the correct location, thus insisting your objective can be reached from inside Markarth.
